我的 WD Elements 外置磁盘通过 USB 3.0 电缆连接，无法访问。我尝试使用两个版本的 Windows 和 Ubuntu 16.04 内核 4.6.0。
几天前，磁盘还在工作。然后，在复制数据时出错，磁盘断开连接。此后，它不再工作。它没有显示为设备。
使用 Ubuntu 进行了一些诊断：
- 拔掉电源插头，等了几分钟，然后重新插上电源
- 使用每个可用的 USB 插槽
- 使用了两根不同的电缆，两根电缆都适用于其他设备
mount没有列出设备sudo fdisk -l没有列出设备- Ubuntu GUI 中的磁盘程序未列出该设备
lsblk没有列出设备sudo blkid没有列出设备lsusb没有列出设备usb-devices没有列出设备- 还尝试安装设备系统救援光盘
我也这样做了（但没有成功）：sudo apt-get install mtp-tools mtpfs
输出sudo lshw

是否有任何软件可以从无法安装/找到的驱动器恢复数据？（DDrescue、Testdisk、photorec ......）
欢迎任何建议！
答案1
我很遗憾听到这种情况！请尝试以下操作：
- 查看设备管理器是否识别它，以及磁盘管理。
- 尝试使用以下方法检查驱动器是否可见WD Data Lifeguard 诊断工具。
还：
- 查看 BIOS 中是否显示该驱动器
- 在其他计算机上尝试驱动器
- 检查振动以查看磁盘是否在机柜内旋转
如果数据非常重要，最好的办法是联系数据恢复公司，以获得最高的恢复数据的机会，但请记住他们的服务可能很昂贵。
使用第三方数据恢复工具可能有效，但也有风险，因为它们可能会进一步损坏您的数据，并且如果驱动器出现硬件问题，任何测试或恢复驱动器的尝试都可能进一步损坏它。
